UNITED STATES FREDERICK BILLINGS, OF WEST ALLIS, WISCONSIN.

PROTECTOR GA]? FOR GAS TANKS.

Application filed December 13, 1923. Serial No. 680,440.

To all whom it may concern:

Be it known that I, FREDERICK BILLINGS, a citizen of the United States, and resident of IVest Allis, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Protector Caps for Gas Tanks; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to protector caps for gas tanks.

Objects of this invention are to provide a protector cap for a gas tank which may be permanently left in place, which permits the use of the tank without altering or removing the cap and which will fully and adequately protect the valve of the tank from damage during shipment.

Further objects are to provide a protector cap for a gas tank which may be readily applied to the tank, which may be produced with a minimum of machine work, and which will be securely retained in position.

Embodiments of the invention are shown in the accompanying drawings, in which Figure 1 is a view of the gas tank with the cap applied,the cap being shown in section, such view corresponding to a section on the line 11 of Figure 8.

Figure 2 is a front view of the structure shown in Figure 1.

Figure 3 is a plan view of the cap in position, such view being partly in section.

Figure 4; is a view of a modified form of the invention.

The portable gas tank 1 is provided with a neck 2 which, at its upper nd, terminates in an outward projecting collar 3 spaced from the body of the tank. This neck portion is internally threaded and receives the downwardly extending portion 4: of the valve 5, such valve being provided with a laterally extending threaded member 6. At the upper end of the valve, a short valve stem 7, equipped with a square portion 8 is provided,this squared portion being adapted to receive the socketed portion of a removable valve wrench or valve stem.

The protector cap comprises a front half section 9 and a rear half section 10, each provided with inwardly directed flanges 11 which are adapted to be fitted beneath the flange 8 of the tank. These members are provided with apertures certain of which are threaded, adapted to receive screws 12 whereby the two half sections may be held together in place upon the tank.

The front member 9 is provided with an aperture 13 which provides access to the threaded fitting 6 of the valve. The top of each of the sections is equipped with a semi circular cutout which, together, form a circular recess 14 (see Figure 1) adapted to permit the entrance of the wrench or removable valve stem through the cap.

In the modified form shown in Figure 4:, the aperture 13 in the protector cap, which corresponds to the aperture 13 in the first form is internally threaded. This threaded aperture is adapted to be closed by a removable screw threaded plug 15 to further protect the valve, particularly during shipping. Obviously, if desired, the upper opening 14 could also be threaded and provided with a removable screw threaded plug in a manner similar to that provided for the opening 13.

It is to be particularly noted that this cap may be permanently left in place on the tank and that the tank may be used in its usual capacity without alteration or removal of the cap. The opening 13 provides suiiicient space for the easy insertion of the conneeting portion of the discharge pipe and the opening 1%: permits the ready entrance of the socketed removal valve stem.

It will be seen that a protector cap for gas tanks has been provided which may b most readily produced, which is of sturdy and substantial construction, which may be permanently positioned upon the tank in a simple and easy manner and which provides the necessary freedom for the manipulation of the valve.

Although one form of the invention has been described in considerable detail, it is lOO cess to said laterally extending portion, and i an upper opening giving access to said valve stem, said protector cap being formed of two half sections each having inturned flanges adapted to be positioned beneath the upper flanges ofsaid neclg a'nd securing means for holding said half sections to- L v F7 Ifir 2.
